+### 20190305:
+
+New customizable variable `symbol-overlay-displayed-window` is introduced to 
control the overlay behavior at `symbol-overlay-mode`. If it is non-nil, 
occurrences outside the displayed window will not be counted or highlighted.
+
 ### 20170826:
 
 `symbol-overlay-toggle-in-scope` now affects both global and in-scope 
highlighting. `symbol-overlay-rename` now uses the original symbol name as the 
initial text in minibuffer. New command `symbol-overlay-count` for counting 
symbol at point. And other improvements.
